Wow! I should trust my gut more often... WE GOT NEW EGGS!!!
I am 99.9% sure they came from the Tetras. One was in the lay box this morning laying down, getting up and scratching, laying down again, getting up, scratching. I gave up watching and went inside.
We do have (I believe) 6 Red Sex Links that have been laying for awhile and they always lay in the same boxes, like clockwork, and their eggs always look the same.
I went out later and found a lighter colored, skinny egg in the middle of the run. Doing the happy dance!
Later, I went back out to check and there was ANOTHER smaller, skinny and lighter colored egg, this time in a laying box. I'm sure they are not from the RSLs because they look totally different.
I was resigned to waiting a few more weeks, as these pullets are only 15 weeks old.
My daughter will be so happy when she gets back from 4H camp!!!
